PHP function structure issue

Question

I have a function

 function me($a, $b, $c, $d) {
 }

I want to add all this in array by array_push is there a variable enable me do this in one step.

I want echo all this on ($a,$b,$c,$d) by foreach

I don't know it i will assume any variable in () will equal $anything

 function me($a,$b,$c,$d){
   foreach ($anything as $key => $value){
     echo $value; // i want return $a,$b,$c,$d values
   }
 }

Any one understand what I want? I want foreach the function and I cant explain because I don't understand

function(void){
  foreach(void) { }
}

I want foreach all variables between () OK in function**(void)**{

You should rewrite your question. I read it twice and found it extremely difficult to understand. Notice how I have used fullstop... you can also use commas in your question. — Layke

I guess that you are talking about variable number of arguments. This example below is from the php site and uses func_num_args to get the actual number of arguments, and func_get_args which returns an array with the actual arguments:

function me()
{
   $numargs = func_num_args();
   echo "Number of arguments: $numargs<br />\n";
   if ($numargs >= 2) {
       echo "Second argument is: " . func_get_arg(1) . "<br />\n";
   }
   $arg_list = func_get_args();
   for ($i = 0; $i < $numargs; $i++) {
       echo "Argument $i is: " . $arg_list[$i] . "<br />\n";
   }
}

me (1, 2, 3);

You could try func_get_args(). Calling that will give you an array (numerically indexed) containing all of the parameter values.

I don't really understand what you are asking, though.

func_get_args() returns all arguments passed to the function.

You can use func_get_args() like Jasonbar says:

function a() {
    foreach (func_get_args() as $param) {
        echo $param;
    }
}

a(1,2,3,4); // prints 1234
a(1,2,3,4,5,6,7); // prints 1234567
